To plot the points $\frac{9}{2}$ and $-\frac{7}{2}$ on the number line:

1. Convert to decimal form:

   • $\frac{9}{2} = 4.5$
   • $-\frac{7}{2} = -3.5$

2. Locate the points:

   • The point $\frac{9}{2} = 4.5$ should be placed halfway between 4 and 5 on the number line.
   • The point $-\frac{7}{2} = -3.5$ should be placed halfway between -3 and -4.

By marking these points at 4.5 and -3.5 on the number line, you'll have the correct locations for $\frac{9}{2}$ and $-\frac{7}{2}$.
